Two types of material are used to make this toy. Starting with the ends, they are made of a chrome plastic which is easy to clean and has no smell or taste. The plastic is smooth, however there are 2 grooves on each side of the balls. I did not feel like grooves added any extra pleasure. The shaft, if you will, is made of silky smooth TPR. TPR is a thermoplastic rubber that is a rubber polymer blend. It has a soft, smooth, velvet feel but no taste or smell. TPR is more porous than silicone, so if sharing, use a condom. TPR cannot be boiled, so when cleaning this toy, I recommend your favorite toy cleaner or soap and water.
The texture didn't add any extra feeling to this toy. I like that the shaft bends, and the balls are stiff. This makes it flexible to use when playing with your partner or solo. It gives it an option to move, rather than just two balls held together by something stiff.
As stated above, I really like that this toy is flexible. The toy itself is 5 1/2 inches long, and the balls are 1 1/2 inches in diameter. Only one ball should be inserted when playing with this toy. The top ball has a sensor at the tip of the ball. This sensor is turned on when the on button is set. To set the on button, you move the plastic portion of the lower ball to the right (clock-wise), so the arrow above the on sign meets with a small arrow facing down on the TPR position. This arrow is hard to see. I wish it was outlined somehow. Now once the toy is on, vibrations will not happen until the sensor is shielded or covered. Once inserted, the vibrations will stay on until the sensor is uncovered, or until the toy is physically turned off by moving the plastic to the left, back to the off position.
The on/off option being on the bottom ball is why I do not recommend inserting the whole toy. I have no complaints about the size of the ball - it's filling and satisfying - but because I did not insert both, it's hard to walk around with the other ball not inserted. This is why I do not recommend this toy for uses like Ben Wa balls.
When I got this toy, I automatically thought, "Oh vibrating Kegel muscle balls." I was kind of wrong. I never use this toy outside if the bedroom like I do with my Kegel muscle toys. The performance is awesome. I used this toy for masturbation with another toy and partner play for a little DP action. The vibrations are strong and loud. Being so loud, I walked around my room with the toy in, and you could hear the vibrations. Walking around with the toy off was fine, but the other ball stuck out and was uncomfortable. I felt like the sensor is very touchy; sometimes when I turned it on, the vibrations turned on when the sensor wasn't covered at all.
Overall, I love the performance and the use of the toy vaginal or anal. It is a great toy to have for masturbation, for the added vaginal bonus while using clitoral stimulation, or to add extra fun for partner/couple play.
Care and maintenance for this toy is easy. Clean with your favorite toy cleaner or soap and water, and store it in the small, soft, tie pouch that came with the toy...easy cleaning and easy storage.
I loved the way this toy was packaged. It was an inviting design, and it gave a lot of info about the company and other toys they offer. The toy also came with a storage pouch which is always a good thing. Care and directions on how to use this toy were easy to read and understand. If you wanted, you could also use the box to store it in as well.
